From: Daniel Gomez <da.gomez@samsung.com> macOS hosts do not include endian.h header required for gen-hyper object. Add a copy of the include/endian.h from the GNU C Library (glibc), version glib-2.40 into include/endian and a copy of bits/ uintn-identity.h into include/endian/bits and update the gen-hyper Makefile to include the library path. Remove the following from glibc include/endian.h:
